The U. S. Consumer Product Safety Commission (CPSC) warns that children should not wear bike helmets when playing, especially on playground equipment. CPSC has reports of two strangulation deaths to children when their bike helmets became stuck in openings on playground equipment, resulting in hanging. CPSC also has reports of four cases where no injury occurred. In two of these cases the children were climbing trees, and in the other two cases, the children were on playground equipment.
Children should always wear helmets while riding their bikes. But, when a child gets off the bike, take off the helmet. There is a "hidden hazard" of strangulation if a child wears a helmet while playing on playground equipment. http://www.cpsc.gov/cpscpub/pubs/5121.html
